2. Given a 2-level Gaussian pyramid, whose level 0 is a 4 x 4 image shown in Table. 1, calculate level 1 of the Gaussian pyramid. Use bilinear interpolation when subsampling an image; use a 3 x 3 Gaussian kernel ( 1, -0) when blurring an image (pad the image before applying the Gaussian kernel). 10 30 10 50 0101101100 0 10 2000 10 20 50 10 Table 1: Level 0 of a Gaussian pyramid. 2.
